"An admirable account of the mechanism of both speech and song. There is a full description of the physiological mechanism concerned in the formation of vowel tones and the sounds of consonants. The action of the vibrators (the vocal cords) and the management of the resonator (the cavities of the pharynx, mouth, nose. &c.), is illustrated by exercises which a reader can easily follow, and the rules to be attended to in the management of the breath are given with physiological explanations. Two notable features of the book are a pronunciation chart showing methods for the practice of English pronunciation, and figures termed by the author 'Song diagrams,' showing the capacity of the various kinds of voices from deep bass to high soprano."
